We're dividing 948478 by 20 
Let's see how many times 20 fits into 948478.

Moving on to step 1:
When dividing 9 by 20, we get 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Fetch the next digit (4) from the dividend, attach it to 9 and continue: 94 / 20

Going ahead to step 2:
20 goes into 94 4 times with a remainder of 14.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 14 after subtracting 80 from 94.
Include the next digit (8) from the dividend after 14, then repeat: 148 / 20

On to step 3:
When dividing 148 by 20, we get 7 with a remainder of 8.
Use 7 as the next digit of our solution. 
Result so far: 47.0
Subtract 140 from 148 to get 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 20

Let's proceed to step 4:
When dividing 84 by 20, we get 4 with a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 474.0
The remainder is 4 after subtracting 80 from 84.
Grab the next digit (7) from the dividend, add it to 4, then carry on: 47 / 20

Let's proceed to step 5:
When dividing 47 by 20, we get 2 with a remainder of 7.
The number 2 becomes the next digit in our result. 
Result so far: 4742.0
If we subtract 40 from 47, we get 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 20

Going ahead to step 6:
78 divided by 20 is 3 with a remainder of 18.
Put 3 as the next digit of the answer. 
Result so far: 47423.0
Subtracting 60 from 78 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 7:
The number 20 fits into 180 9 times, leaving a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 47423.9
Deduct 180 from 180 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
If we divide 0 by 20, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 47423.9
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
20 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 47423.9
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 47423.9 with a balance of 0.0.
